I was in the middle of submitting a support request (I couldn’t log in to my email account, an extremely rare occurrence) but before I finished I figured I’d give it another try. Sure enough, the problem was fixed before I even finished submitting the request! I am impressed.

Sometimes the problems have already been solved when DH support gets back to me.

Don’t be fooled. That’s usually because DH has the policy that, generally, their support people don’t reply to the original bug report until it’s actually been investigated and the cause of the problem determined.
